Just thought that I would chime in here and say that this is definitely a WiFi interference issue. On my Dell XPS 9550 (bcm20703a1 bluetooth chipset) I would get really bad choppy, de-synced audio sometimes. I finally figured out that whenever it was happening, I was connected to a 2.4 GHz WiFi network. Connecting to a 5GHz WiFi network solved the problem.

[Broadcom Corp. BCM20702 Bluetooth 4.0] Status in bluez package in Ubuntu: Invalid Bug description: This is the same problem in https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/405294 and even though I have pulseaudio 12.2 (on Xubuntu 18.10), this problem persists (this T430 laptop has inbuilt Bluetooth). This makes listening to music or any audio over Bluetooth almost unbearable - while it is temporarily fixed by running `pactl suspend- sink 1 && pactl suspend-sink 0` it soon returns. I have even updated the BIOS but the problem persists.
